VENEER MACHINE.

Applicationfiled April .27, 1928. Serial No. 273,277.

This invention relates to improvements in veneer machines, and moreespecially to the chuck and stay log of such a machine. v

One of the features of my invention is the provision of a rigid, stiff,stay log that does not how or yield during the cutting operation.

2 Another feature of my invention is the provision of improved chuckspermitting quick and eas adjustment of the log with respect to theknife.

Other features and advantages of myjinveution will appear more fully asI proceed with my specification.

In that form of device embodying the features of my invention shown inthe accompanying drawings, Fig. 1 is a view in front elevation, Fig. 2is a view taken on the line 2 of Fig. 1, Fig. 3 is aview takenon theline 3 of Fig. 1, Fig. 1 is a view taken on the line 1 of'Fig. 2, Fig. 5is a vertical sectional view of a chuck and bracket, Fig. 6 is a viewtaken as indicated by the line 6 of Fig. 1, Fig.7 is a broken plan viewof one of the brackets, and Fig. 8 is a view taken on the line 8 of Fig.1.

As shown in thedrawings, 10 indicates in general an ordinary type ofveneer machine to which my inventions may be applied. Such machines, ingeneral, are old in the art and consequently it will not be necessary todescribe one here, except as may be necessary to explain my inventions.senibles, to a certain extent, a lathe and is provided with the usualrotatable chuck spindles 11 and .12 which are adjustable towardand awayfrom each other to accommodate logs of different lengths. 13 indicatesthe knifewhich cuts the sheets of veneer from the log as it is rotated.

Each spindle carries a chuck 14; which in turn carries a bracket 15 tosupport one end of the stay log the end piece 15 and supporting piece15. Since the chuck and bracket at each end of the machine are the same,I shall describe but one.v

The face of the chuck 14: is provided with teeth to engage the end ofthe log 18. These I teeth comprise circular pro ecting members 17 eachhaving a'concave depression 19 at its end. I have found that teeth ofthis form give a very firm grip on the log with practically notendencytojsplit the same. v

The bracket 15 is adjustably mounted on the chuck so that logs ofdifferent thicknesses Such a machine re- 16. The bracket 15 includes maybe accommodated and so that the proper adjustment toward and away fromthe knife may be accomplished as the cuttingprogresses! The sheets ofveneer 20 are cut from the log ecceutrically, as shown inFig. 6,'and

1 when one side has becncut near enough toward the center the leg isturned over.

1 x z r The ad ustment of the bracket 15 is provided for as follows Theface of the chuck 1.4L

has two keyhol'es or undercut parallel slots 21' lying at each side ofthe center. Outside of tl'iese 'SlOtS and parallel therewith are twoguide ribs 22 between which the end piece 15 the bracket 15 may slide asit is adjusted.

The bracket 15 is held firmly inits adjusted positions by two bolts'23passing through the end piece 15 with their squared heads 23 lying intheslots 21. 23 indicates a nut on each bolt 23', which, when tightened,holds the bracket firmly against the face of the chuck.

The bracket 15 is adjusted or slid between the guide members 22 by meansof a screw 2a threaded into the end piece 15 and passing through alug 25on the face of the chuck. V

Y The screw 25 is provided with acollar 2 1*" resting on the lug 25. Itis to be understood that the nuts 23 are loosened before the bracket isadjusted and then tightened to hold ing plate 15 of each bracket isprovided with slots 15 to accommodate bolts 26 for fastenthe stay logand toperinit adjustment of the brackets toward and away from each thesame firmly in position. The'supportother. This plate is also preferablypro,- N

vided at its edges with rai ed flanges '15 l3' tween which the end ofthe stay loglies.

The staylog, ndicated in generalfby 16,

comprises an I-beain 16 having attached to it a channel 16 above and aplate 16? below. The channel is somewhatnarrower thanthe I- beam andblocks 16 are placed between the flanges thereof and held in place inany suitable manner, as by welding. The plate 16 is just wide enough tolie on the supporting plate 15 of the bracket 15 between the flanges 15.The log 18 rests on the channel 16? of the staylog and its ends aregripped by the teeth 17 on the chucks. The log is additionally held byone or more lag screws 27 passing through the stay log, midway of itsedges.

While I have shown an'd'describ'ed certain embodiments of my invention,it is to be un:

'derstood that it is capable of many modificas tions- Changes,therefore, in the construction and arrangement may bemade without onsaid staylog.

departing from the spirit and scope of the invention as disclosed 1n theappended clalms,

in which it is'iny intention to claim all novelty inherent in-myinvention as broadly as posthe underside thereof, the end of said. plateadapted to rest on the supporting plate of the bracket and fit snuglybetween the raised flanges at the edges thereof.

In combination with mechanism as claimedin claim 2, a lag screw projecting through the stay log, midway of itsedges, and adapted to project into a log supported on the stay log.

5. In a veneer machine of the character described; a chuck having itsface provided "ith an undercutslot; a bracket radially adjustable on thechuck, having an end piece lying against the'face of the chuck and aplate adapted to support the end of a stay log; a bolt passing throughthe end piece of the bracket With its head lying in the slot in the 2106of the chuck and adapted to be tightened to hold the bracket tightlyagainst the face oi the chuckin its adjusted position; two

parallel guideribs on the face of the chuck adjacent the sides otthe endpiece oi the bracket; and means tor radially adjusting the v bracket onthe chuck; said bracket adapted to slide between said guide ribs whilebeing adjusted. I
